Circuit & System Protection
AVX has introduced a new series of high-temperature, low-leakage automotive varistors. Qualified to AEC-Q200, the CANATL series of automotive CAN varistors exhibit extremely low leakage (≤1 μA at 32 V d.c., 25°C) and are tested, qualified and specified at 150°C, making them ideal for use in underhood automotive applications such as transmission control units (TCUs), brake control modules (BCMs), data lines, bus interface units and other capacitance sensitive applications.
Based on AVX’s patented multilayer varistor (MLV) technology, which combines circuit protection and EMI/RFI attenuation functions in a single, high-reliability device, CANATL varistors are zinc oxide based ceramic semiconductor devices that exhibit non-linear, bidirectional voltage-current characteristics similar to back-to-back Zener diodes and an EMC capacitor in parallel.
In addition to the space savings provided by enabling EMI/RFI attenuation in the off-state, CANATL series multilayer varistors provide several valuable performance advantages over diodes, including high in-rush current capacity (8 x 20 μs), a high 25 kV (HBM Level 6) ESD rating, low capacitance (10 pF) to minimise signal distortion, no derating over operating temperatures, and very fast response times, which conservatively clamp the energy before it reaches its maximum. They also exhibit multi-strike capability, excellent solderability, and an impressive FIT rate of ≤0,1 per billion hours.
Rated for use in temperatures spanning -55°C to 150°C, CANATL series automotive varistors are currently available in a 0603 case rated for 32 V d.c. operating voltage.
